perl-ExtUtils-XSBuilder (automatic XS glue code generation)

XSBuilder is a set modules to parse C header files and create XS
glue code and documentation out of it. Idealy this allows to "write"
an interface to a C library without coding a line. Since no C-API is
ideal, some adjuments are necessary most of the time. So to use this
module you must still be familar with C and XS programming, but it
removes a lot of stupid work and copy&paste from you. Also when the
C API changes, most of the time you only have to rerun XSBuilder to
get your new Perl API.
